Background technique
Feed is the material base for developing modern farming enterprise's and culture fishery, is the important composition of modern agriculture industry system
Part, have in national economy particularly important status (status of Ding Qiang, Wang Zhengnan the feed industry in national economy with
Influence the research of [J] feed, 2010 (2): 13~14).China's feedstuff industry starting evening, but demand is big, development is fast, and 2016 are complete
State's feed total output is about 2.1 hundred million tons, it has also become the most important Feed Manufacturing state in the whole world (whole nation All-China Livestock General Station .2016
Feed industry counts overview [J] China feed, 2017 (13): 1~2).
Granulation refers to by mechanically or chemically, by powdery or liquid charging stock polymerization forming.During feed processing, powder
Shape feedstuff or mash feed are quenched by hydro-thermal, via the mechanical parts squeezing action such as mold roller, so that feed is forced through
Die hole and molding bonded.Feed by granulation processing has the advantage that 1. avoidable animal is particular about food；2. return on feed
It is high；3. storage transport is more economical；4. good fluidity, convenient for management；5. can avoid heterogeneity layering, environmental pollution is reduced；
6. killing the salmonella etc. in animal feed.Granulation is important process during modern feed processing, is the main of feed
Forming technique.
Current granulator has the disadvantage in that material to be pelletized directly by loose condition (of surface) is squeezed into compacted state by 1.,
There are biggish internal stress for particle after granulation, there is the problems such as rate containing powder is high, energy consumption is high, pellet durability degree is low；2. due to
The reasons such as loose material pan feeding and cloth to be pelletized is uneven, is deposited near die hole, cause at phenomena such as being easy to produce stifled machine
The waste of raw material reduces production efficiency；3. granulator mostly uses the structure of a ring moulds and two pressure rollers on the market, ring moulds with
The abrasion of pressure roller is very big, therefore there is the problems such as energy consumption, service life is short.

Lower end be fixed on the rack.
Often there is the problems such as rate containing powder is high, energy consumption is high, pellet durability degree is low in existing granulator, reason is through toning
The moisture content range of material is generally 15%-18% after matter, and material is in loose state at this time, and there are larger between material powder
Gap, compacted state of the material directly after squeezing and becoming densification from loose condition (of surface) in traditional pelletization, after granulation
There are biggish internal stress, particle inside itself can have elastic expansion and elastic hysteresis behavior for grain, will lead to particle appearance
Crackle and then the initiation above problem.For this programme by the way that described screw rod one end to be mounted on operation door, the other end is located at machine barrel
It is interior, extrusion cavities are provided on the side wall of machine barrel rear end, such material during inside machine barrel moves, is realized by screw rod
Material homogeneous and pressure maintaining are handled；As material enters the cavity of machine barrel rear end, the cavity of machine barrel rear end forms partial high pressure area
Domain, material are further squeezed out by the extruded hole of machine barrel rear end cavity, and then complete first stage granulation；First stage obtained
Intragranular portion is comparatively dense, and internal stress is smaller and substantially nonelastic swelling.In addition, the internal diameter of extrusion cavities radially by interior and
It gradually becomes smaller outside, such structure designs so that material is in machine barrel extrusion process, and stress and internal organizational structure variation are uniform.
Then, the material of first stage primary compression enters the granulation region between machine barrel and ring moulds, in squeezing for pressure roller group and ring moulds
It under pressure effect, is squeezed out by the die hole in ring moulds, completes second stage granulation.The granulator of this programme reduces in particle presence
Portion's stress and elastic expansion stress avoid material and contain existing for granular powder intergranular when directly becoming densifie state from loose condition (of surface)
Powder rate is high, energy consumption is high, the low phenomenon of pellet durability degree, improves utilization rate of equipment and installations, has saved energy consumption, reduces pellet because of powder
Change and caused by waste.
Preferably, material guide channel is located at the outside of the operation door, and material guide channel is equipped with opening, is open and lacks for a rectangle
Mouthful, open lower end is equipped with an ear connected in star.This design, convenient for carrying out the operation such as material observation, sampling in opening；Meanwhile
When inlet amount is larger or granulator blocks up machine, discharge can be played the role of.
Preferably, the diameter of spiro rod rear end is gradually increased, and screw pitch is gradually reduced.
Preferably, the number of the pressure roller of pressure roller group is 5.
Preferably, the diameter range of extrusion cavities is φ 8-15mm, and the axial length of extrusion cavities is 2-4 times of its internal diameter.
Preferably, the diameter range of die hole is φ 1.5-8mm, and the axial length of die hole is 6-9 times of its internal diameter.
Preferably, the inside diameter ranges of machine barrel are φ 250-300mm；The inside diameter ranges of ring moulds are φ 750-900mm.
Compared with prior art, the utility model has the following beneficial effects:
(1) the utility model is pelletized using two stages, is provided with extrusion cavities, screw rod and machine barrel energy on the side wall of machine barrel rear end
Enough realize handles the homogeneous of material and pressure maintaining；Material enters the cavity of machine barrel rear end, forms partial high pressure area in machine barrel rear end
Domain, material are squeezed out by the extruded hole of machine barrel rear end cavity, complete first stage granulation；Inside particle made from first stage more
Densification, internal stress is smaller and substantially nonelastic swelling.Then, the material after first stage granulation enters machine barrel and ring
The second stage granulation region of intermode is squeezed out under the squeezing action of pressure roller group and ring moulds by the die hole in ring moulds, completes second
Stage granulation.This programme reduces particle, and there are internal stress and elastic expansion stress, avoid material directly by loose condition (of surface)
Become when densifie state that the height of rate containing powder existing for granular powder intergranular, energy consumption is high, the low phenomenon of pellet durability degree, improves feed product
Matter, waste caused by reducing pellet due to dusting.
(2) screw rod plays the role of conveying and extruding simultaneously in the utility model, on the one hand can improve traditional system
The physical behavio(u)r of the random bulk deposition of material to be pelletized avoids so that material to be pelletized moves in an orderly manner in machine barrel in grain machine
Loose material bulk deposition to be pelletized is between ring moulds and pressure roller, phenomena such as resulting in blockage；On the other hand by screw rod itself,
The extrusion cavities of screw rod and machine barrel, machine barrel side wall, squeeze material to be pelletized tentatively, volume primary compression, improve next stage
The operating efficiency of ring moulds pressure roller granulation.
(3) form a high-pressure area in the utility model screw rod and machine barrel, granulation second stage in ring moulds and
Negative pressure region is formed between machine barrel, by the pressure difference of high pressure and negative pressure, is conducive to material and is squeezed out from the extrusion of machine barrel, it can
Avoid extrusion blockage phenomenon.
